The threaded connection structure is cumbersome to dock, and the installation is complicated, the workload is large, and the installation speed is slow. Especially in certain specific installation environments, the installation process becomes particularly time-consuming, which is not conducive to the rapid installation of the cup comb.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Example 1

[0028] This embodiment discloses a wire tube cup comb, referring to Figure 1-Figure 4 As shown, it includes a cup comb body 100, a convex ring part 4 and a limit block 5. The cup comb body 100 has a three-section structure, including a first cylindrical part 1, a transition part 2 and a second cylindrical part 3, wherein the outer diameter of the second cylindrical part 3 is larger than the outer diameter of the first cylindrical part 1, the transition part 2 is connected between the first cylindrical part 1 and the second cylindrical part 3 to form a transition of the outer peripheral contour, and the outer diameter of the transition part 2 gradually increases toward the second cylindrical part 3.

[0029] Generally, the outer wall of the transition portion 2 is a cone-shaped structure, and the outer peripheral contour of the small diameter end of the transition portion 2 is consistent with the outer peripheral contour of the first tubular portion 1, and the outer peripheral contour of the large diameter end of the transition portion 2 is consistent with the outer peripheral contour of the second tubular portion 3. Under the transition effect of the transition portion 2, a relatively smooth structure can be formed between the three tubular structures of the cup comb main body 100.

[0030] The convex ring portion 4 is fixedly connected to the outer periphery of the second cylindrical portion 3, specifically located at the outer periphery of the first cylindrical portion 1. A stepped structure is formed on the outer periphery of the first cylindrical portion 1 to form a positioning with one side of the switch box.

[0031] The limiting block 5 is elastically connected to the cup comb body 100, and the cup comb body 100 can be elastically deformed in the direction of the cup comb body 100. The limiting block 5 includes a limiting surface 51, and the limiting surface 51 faces the convex ring part 4. At least a part of the limiting surface 51 can protrude from the outer periphery of the cup comb body 100. The limiting surface 51 of the limiting block 5 forms a positioning with the other side of the switch box, and a limiting groove 7 is formed between the convex ring part 4 and the limiting surface 51. During installation, the cup comb body 100 can pass through the side wall of the switch box, and the convex ring part 4 and the limiting surface 51 can be blocked on both sides of the side wall of the switch box respectively, so that the cup comb body 100 is clamped with the switch box, and the cup comb body 100 is fixedly installed.

[0032] Reference Figure 3 As shown, the stopper 5 includes a connecting end 501 and a free end 502. The connecting end 501 is connected to the cup comb body 100, while the free end 502 extends toward the convex ring portion 4. Furthermore, the direction of the stopper 5 aligns with the direction of the transition portion 2. The free end 502 is elastically deformable in the direction of the cup comb body 100. The limiting surface 51 is located at the free end 502, and the free end 502 is used to achieve a snap connection with the switch box. Generally, there are two stoppers 5, symmetrically distributed, enabling snap connection from two directions, ensuring a stable snap connection between the cup comb body 100 and the switch box.

[0033] The cup comb body 100 defines a through-hole 6 extending through the sidewall of the cup comb body 100. A portion of the stopper 5 is located within the through-hole 6. When uncompressed, the stopper 5 protrudes from the sidewall of the cup comb body 100. When compressed, the stopper 5 elastically bends inwardly from the through-hole 6, allowing it to yield.

[0034] The connection end 501 of the limiting block 5 is connected to the inner wall of the through-opening 6 , and the outer peripheral contour of the connection end 501 coincides with the outer peripheral contour of the transition portion 2 .

[0035] The through-opening 6 is partially opened in the transition portion 2, and the outer side of the stopper 5 forms a guide surface 52, which is adapted to the direction of the transition portion 2. The through-opening 6 is partially opened in the second cylindrical portion 3, and the free end 502 of the stopper 5 protrudes from the outer periphery of the second cylindrical portion 3.

[0036] During the installation of the wire tube cup comb, the first cylindrical part 1 of the cup comb body 100 is passed through the wire threading hole of the switch box. Since the outer diameter of the first cylindrical part 1 is smaller than the wire threading hole, the cup comb body 100 can be smoothly inserted; then, as the transition part 2 gradually passes through the wire threading hole, the guide surface 52 on the outside of the limit block 5 will abut against the wire threading hole, and then the free end 502 of the limit block 5 can be elastically deformed toward the inner circumference direction of the cup comb body 100, so that the width of the two limit blocks 5 becomes smaller, and then the limit block 5 can be clamped to the wire threading hole of the switch box, and the side wall of the switch box is adapted to the limit groove 7 to achieve clamping and fixation.

[0037] Further, refer to Figure 5 As shown, the outer diameter of the second cylindrical portion 3 needs to be designed based on the width of the threading hole in the switch box, so that the cup comb body 100 can maintain a stable engagement when it is inserted into the threading hole in the switch box. The outer diameter of the first cylindrical portion 1 only needs to be smaller than that of the second cylindrical portion 3, and the thickness of the second cylindrical portion 3 can be adjusted to meet actual threading needs.

[0038] Example 2

[0039] This embodiment discloses a wire tube cup comb, based on the first embodiment, and referring to Figure 6 Detailed description is given. The through-opening 6 forms an inner side wall 61 on the side close to the convex ring portion 4, and the inner side wall 61 is opposite to the limiting surface 51. When the limiting block 5 is not under pressure, the inner side wall 61 and the limiting surface 51 are roughly parallel, and a narrow gap is formed between the two, and the gap width is 1-2mm. When the limiting block 5 is under pressure and deformed in the inner circumferential direction, the limiting surface 51 of the limiting block 5 will be slightly deformed and bent toward the upper side, so that the limiting surface 51 will be against the inner side wall 61. The inner side wall 61 can block the limiting surface 51 and limit the deformation of the limiting block 5.

[0040] Furthermore, a protrusion 611 is formed on the surface of the inner sidewall 61, and an elastic strip 612 is connected to the side of the protrusion 611 facing the limiting surface 51. The elastic strip 612 is elastically deformable and can elastically press against the limiting surface 51 of the limiting block 5, thereby elastically blocking the limiting block 5. The elastic strip 612 and the protrusion 611 not only facilitate the rebound of the limiting block 5, but also increase the elastic force that causes the limiting block 5 to deform and bend, thereby improving the stability of the engagement between the limiting block 5 and the wire threading hole of the switch box, preventing unnecessary disengagement and enhancing the stability of the engagement.

[0041] Furthermore, the elastic strip 612 is connected to the limiting surface 51, which can maintain the position stability of the elastic strip 612. One end of the elastic strip 612 is connected to the protrusion, and the other end is connected to the limiting surface 51. The elastic strip 612 then limits the elastic deformation stroke of the limiting block 5, improving the stability of the clamping connection.

[0042] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
